.SHEARS- SPECIFICATION forming part of Letters Patent No. 760,204, datedMay 17, 1904.

Application filed July 29, 1903. Serial No. 167,485. (No model.)

To all whom it may concern:

Be it known that I, VIRGINIA HEINISOH, (ad- Ininistratrix of the estateof HENRY C. HEIN- IsoH, deceased,) a citizen of the United States,

in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to numerals of referencemarked thereon, which form a part of this specification.

This invention relates to certain improvements in that class of shearsrepresented by the one shown in Patent No. 454,7 35, granted Henry C.Heinisch June 23, 1,901, the objects of the present improvements beingto secure a better bearing for the hand in cutting cloth, particularlywhen several plies or thicknesses of cloth are cut at one time, the saiddevice being more particularly useful in connection with tailor-work incutting woolen cloth for mens garments, &c., and to secure more comfortin working for the tailor or other user, the latter being enabled towork with less distress to the hand, and to secure other advantages andresults, some of which may be referred to hereinafter in connection withthe description of the working parts.

The invention consists in the improved shears and in the arrangementsand combinations. of parts of the same, all substantially as will behereinafter set forth, and finally embraced in the clauses of the claim.

Referring'to the accompanying drawings, in which like numerals ofreference indicate corresponding parts in each of the several. figures,Figure 1 is a side elevation of a portion of the improved shears. Fig. 2is a detail section, taken on line 21:, of the upper hand portion, uponwhich the pressure of the hand is brought to bear; and Fig 3 is a planof said hand portion.

In said drawings, 10 indicates the upper blade, with which the lowerhand portion 11 is integrally connected, and 12 indicates the lowerblade, with which the upper hand portion 13 is integrally connected, thesaid blades being pivotally connected by a suitable pivot 14 insubstantially the manner common in tailors shears.

In applying the words upper and lower to the loops for receiving thethumb and tingers and to the cutting-blades 10 12 the supposition isthat the shears are in the ordinary positions for cutting, the blade 12lying on the cutting board or table and the upper hand portion or loop13, through which the thumb is inserted, lying above the loop 11, thepressure of the ball or base of the thumb being exerted on the lowerparts of the upper loop, to which lower parts the present improvementsparticularly relate.

The lower hand portion 11 is similar in construction to the one shown inthe prior patent above referred to; but the upper hand portion 13contains the improvements to which the present invention relates. Of thesaid upper hand portion, 15 indicates the curvilinear upper part, whichlies in practice at the top of the base portion of the thumb, and 16 isthe lower part or member, which lies on the inner or lower side of thethumb and palm of the hand when the latter presses upon the lever-likeblade member 12 13 to effect a cutting of the cloth.

In the prior invention above referred to the part 16 presented on theupper side a regularly-convex surface upon which the operator pressedhis hand, and while this presented a large superficial area,distributing the pressure over a large surface of the palm of the hand,yet, because of its construction, it tended, more or less, to tire thehand after considerable use. In the present construction a concavity 17is formed on the upper surface, adapted to receive the ball of thethumb, and laterally out from said concavity is formed a ridge 18, fromthe outer side of which the said lower part or member 16 is inclineddownward to form a flange 19, the lower part of the upper hand portion13 thus being given a decided angular form, the angle of which on theupper side is rounded to enter the groove or recess in the palm of thehand extending downward oraway from the middle portion of the Wrist.Thus constructed the pressure is distributed more perfectly over thepalm of the hand and serves to prevent the hand from becoming painfulbecause of severe pressure being brought to bear at points on the handdistant from one another. I The downwardly: extending flange 19 is alsoslightly concavous, as at 20, to receive the convex portion of the palmlying opposite the ball of the thumb. The lower part or member 16 of theupper handle extends forward and transversely, so as to cross beneaththe upper part 15, as heretofore, so that the thumb for substantiallyits full length will press downward on a bearing provided therefor. Theincreased effective area thus secured enables one to arrange the pivot 1L nearer tothe handle, and thus to open thevblades more fullypreparatory to cutting, and yet in the cutting operation perform suchoperation without tiring the hand, notwithstanding the increasedfulcrumal resistance or leverage. r I a In addition to the otheradvantages recited the ridge 18 tends to prevent the hand from slippingon the surface of the member 16, as Will be evident.

Having thus described the invention, what is claimed as new is 1. Theimproved shears herein described comprising blades with hand-loopsconnected therewith, the upper loop being concaved on the upper face ofthe lower member, where it receives the pressure of the ball or base ofthe thumb, said lower member of the upper loop being bent downward, theridge or bend being adapted to enter the groove or recess at the centerof the rear part of the palm of the hand, substantially as set forth.

2. In a shears, the looped blade herein described having the lowermember of the loop
